What is the difference between Net Carbs and Carbohydrates?
I’ve had a table of nutrition data for many foods online for a few years now.
The table lists the most popular data that people are commonly interested in – calories, grams of protein, fiber, fat, and total carbs. The table also lists something called “Net Carbs,” which has caused a little confusion. What exactly are Net Carbs?
“Net Carbs” is a measure used the the Atkins diet system that attempts to measure how a particular carbohydrate that impacts blood sugar. The theory of “net carbs” holds that some carbohydrates, such as those from fiber or sugar alcohols, have a smaller effect on blood sugar levels. Counting these carbs separately allows a person on a low-carb diet to feel “full,” thus increasing the effectiveness of the deit.
The formula for calculating net carbs is as follows:
This whole “net carbs” thing is a somewhat controversial measure, and it gets a bit more complicated than the above. I’m no doctor, so I’ll leave the detailed explanation to the experts.

Also if you’re exercising, and you need to eat a certain amount of carbs, fiber and sugar alcohols do not give you energy. They MUST be excluded from your count, or you may run out of energy. So it’s not just for people limiting carbs. It’s for people counting carbs in general.
